WINDIVIILL MECHANISIVL.

Specification of Letters Patent.

Patented ct. 12, 1909..

To all 'whom it may concern.'

Be it known that I, IRA C. RUST, a citizen of the United States, andresiding at Farmland, in the county of Randolph, State of Indiana, haveinvented new and useful Improvements in lVindmill Mechanisms, of whichinvention the following is a specification.

This invention pertains to improvements in power transmitting meanswherein rotary movement is converted into reciprocatory motion, and ithas morel especial reference to mechanisms of wind mills. In this classof mills it is very desirable that the motion furnished by the rapidlyrot-ating wind wheel, shall be so converted and transmitted that themember or rod which operates the pump or other machinery, willA haveimparted to it a positive regular and steady movement.

To accomplish the aforesaid desirable results, are the objects, broadlystated, of my invention.

Further objects of my present invention are to provide a power andmot-ion transmitting means which may be easily rendered inoperative andthe wind wheel may be held against rotary movement.

Other and more specific objects are to provide a device of the kinddescribed which will be substantial and strong, not liable to get out oforder or repair, and which will be economical of construction. and easyof installation.

The aforenamed objects of my invention are accomplished by and myinvention is embodied in the new construction, combination andarrangement of parts described in this specification, defined in theappended claims, and illustrated in the accompanying drawings.

Similar characters of reference refer to corresponding parts throughoutthe several views in the drawings, in which- Figure 1 is a side view,Fig. 2 is an end view, and Fig. 3 is a plan view of my inventioncomplete, the central portion in the first named View being shown insection. Fig. 4 is a detached transverse sectional view of the cammember and upright shaft removed. Fig. 5 is a horizontal plan view takenon the line A Fig. 1. Fig. 6 is a horizontal plan view taken on the lineB Fig. 1.

From the base 1 of the framefof my improved mechanism rise the upwardlydisy posed arms2 and 3.

Journaled. in suitable bearings carriedby the said arms is the shaft 4upon the outward portion of which is se- .cured the hub-of the windwheel and which hub may be of any acceptable style or structure.Projecting from the arm 3 is a lug 5 upon the end of which is fastenedthe fixed end of the brake band 6. This flexible brake band is of properform to engage the peripheral face of the said hub, and its lower end isfastened to the short arm of the lever 7 which is pivotally supportedonthe lug 8. This lever is so formed that the free end thereof willoccupy the position relative to the frame, as plainly shown'in thedrawings.

The bottom portion 2a of the arm 2 has al vertical bore in which theupright shaft 9 is journaled. The upper portion of the arm 2 has a`horizontal bore or recess in which the inner end o f the shaft 4 isjournaled. The center point of the base portion 1 is to onel side ofthecenter line of the shaft so that there will be ample clearance betweenthe said shaft, and the vertical reciprocatory bar 10. As a meansto.sustain the reciprocatory bar 1() in correct central position in thebore 1l of said base portion, there is provided the guide block orbushing 1Q suit.- ably secured in position and having an aperture inwhich the bar 10 is free to move slidingly. The shoe 13 has its upperportion of proper diameter to fit within said central bore, where it isheld by set screws 132 Screwed tightly into the shoe is the hollowupright member 14 which extends downwardly through the. platformk of thetower upon which themill 1s carried. The lower end of this upright isfree to move rotatively but is held against transverse movement by thespider 14a which is secured to the tower structure. The platform 15which is suitably supported in fixed position by the tower structure 16,has a central opening through which the aforesaid upright 14 is easilypassed. Complemental annular races in the facing surfaces of the shoeand the platform form runways between which are disposed the balls 17.By this construction and arrangement of the several parts the frame hasthe usual free pivotal movement, and will be sustained in correctvertical position.

It will be understood that a swivel connection (not shown) ata properlocation inl the rod 10 is provided, so that the rod will by the arm 19is the strong buffer spring 21 the free end of which spring will bearagainst the lug 22 carried by the frame. The normal position of the vanebeam with reference to the frame, when the mill is operating, is thatshown in Fig. 5, the vane beam is held in the position shown, by thecoil spring 23 which has its one end fastened to Ythe arm 19 and theother to the frame proper.

The outer ends of the arm 19a and the lug 22 are suitably widened andrecessed so as to let the coil spring 23 rest and move therein. Carriedby the arm 20a is the buffer spring 24 the function of which willpresently be referred to.

On a bracket 25 carried by the frame, is the grooved pulley 26. A cableor rope that is fastened to the arm 20 is passed over this pulley thenceover a grooved pulley 27 that is carried loosely on the shaft L1, thencedownwardly through the perforation 12a in the guide block 12. This cableis sufficient in length so that a person standing on the ground at thebase of the tower may manipulate same. Then the cable is pulleddownwardly the vane beam will be moved around into the dotted lineposition shown in Fig. .6. As this position of the vane beam is reachedthe windv wheel will no longer stay in the wind and by the pressure ofthe arm 20a against the brake'lever 7, the brake band is quicklytightened against the hub of the wind wheel and the latter will be heldagainst rotation. The attendant may then secure the cable so that thevane beam may be kept in the inoperative position. To prevent undue jarof the frame and to prevent too sudden actuation of the brake lever,when the operation of throwing around the brake beam is performed, asjust described, is the function of the buffer spring 24. With thepulling down of the cable and the moving of the vane beam, as the latterreaches the dotted line position, the buffer spring strikes the baseportion of the frame in advance of the engagement by the arm 2O*l of thelever 7. On the inner end of the shaft et is secured a bevel gear wheel28 which meshes with the gear wheel 29. This gear wheel 29 is looselydisposed on the upright shaft 9, and the upper face of its hub istoothed, as shown in F ig. 1, and Fig. 2 to receive the complementallytoothed hub of the cam wheel 30. The structure and position of this camwheel is plainly shown in Figs. 1, 2 and 3, the

eeases 4by a wind wheel, said cam to actuate a reciprocatory member, isshown in Patent No. 913,918, granted tome March 2, 1909. Since theconstruction of the device shown in said patent, my present inventionhas been developed and perfected.

In the present invention the conformation of the web of the cam wheel issuch that as the cam wheel is rotated, the movement of the reeiprocatorybar 10 is decidedly more rapid in its downward stroke than upon itsupward stroke, the desirability of which is obvious. The time necessaryfor the reciprocation of the bar 10 is so conserved that, (in theproportionate ratio as shown) the lift n'iovement is given two thirds,and the downward stroke one third of the time necessary for the rotationof the cam wheel.

By the new combination, construction and arrangement of the severalparts my invention is rendered of practicable utility for any desiredstroke of the pump piston. Cain wheels having different forms of webs toaccommodate pumps of greater or less stroke, or for pumping material ofvaried specific gravity, may be supplied. The upper portion of the hubof the cam wheel is of such length that when the to i member 33 whichforms the upper boxing for the upright shaft 9, and the guide head forthe reciprocatory bar l0, is bolted into position on the upper end ofthe arm 3, the parts will all be retained in the correct position asshown, and the frame will be complete.

It will be understood that minor changes may be made in the conformationand detail construction and arrangement of the several parts, within thescope of my invention as the same is defined by the appended claimswithout departing from the nature or spirit of my invention, and withoutsacrificing any of its advantages.
